xorg@xxxxxxxxxxxxxxx or the fedora users list would be better for follow up
as the root of your problem has nothing to do with KDE.

When I upgraded to Fedora 12, I had similar problems getting the resolution to 1280x1024, I had to use system-config-display and create an xorg.conf file and add nomodeset to my kernel boot line in grub to get it to work.
> Fedora 14 has deprecated system-config-display; if I add nomodeset to the kernel line, I don't get a login screen and everything I've tried so far has not worked -- at least I have 1024x768 resolution -- with Fedora 12 it defaulted to 800x600.
There is no more nomodeset option for Intel video users.

Delete all above sections. They have nothing to do with your problem.
Automatic works for them for most people.
> Section "Module"
> Load "record"
> Load "glx"
> Load "dri2"
> Load "dri"
> Load "extmod"

The above section is probably no longer necessary. Depends on which chip you
have maybe.

Try adding to above section 'Option "PreferredMode" "1280x1024"
> Section "Device"
> ### Available Driver options are:-

You can see most of those are commented away. Uncommenting NoDDC might have
an impact. BusID is probably not needed.
Be sure on follow up to tell exactly which Intel chip is reported by lspci.
> Section "Screen"
AFAICT, this whole section is obsolete for Intel chips, but may be useful for
some older chips like MGA.

Fedora 14 maybe impacted by
https://bugs.freedesktop.org/show_bug.cgi?id=32430 unfixed but in need of
fix, meaning you may need to move your configs into /etc/X11/xorg.conf.d/ for
them to work. You may want to search bugzilla.redhat.com first for a bug
referencing 32430.
If none of the above helps, adding xrandr commands to /etc/X11/xinit/xinitrc
may be your solution.
